ABSTRACT TMS320C80 is one of the most powerful multimedia video processors in the world, which integrates a RISC main processor with standard floating point processing unit, four advance parallel DSPs, an intelligent transfer controller, and a video controller. It's capable of processing video in real-time.

TMS320C80是世界上功能最强的多媒体视频处理器之一，在单一芯片上集成了一个带标准浮点运算单元的RISC主处理器、四个高级的并行数字信号处理器、一个智能的传输控制器和一个视频控制器，具有强大的实时视频处理能力。

In order to reduce the periodic current tracking error of the deadbeat control when compensating abruptly changing nonlinear load current, a repetitive controller is plugged into the deadbeat controller. Also, the repetitive controller can alleviate the parametric dependency of the deadbeat control and eliminate the effects on compensation performance caused by the uncertainties in the system.

另外，为了降低无差拍控制对系统参数的依赖型和系统中存在的不确定性对补偿性能的影响以及减小在补偿电流变化剧烈的非线性负载电流过程中存在的周期性的局部跟踪误差，本文在无差拍控制器的基础上，又提出了基于无差拍和重复控制的复合电流控制器。

Simulation results show that the servo system with the designed controllers provides a good performance. At the same time, it reduces the sensitivity of the system performance to the controller parameter perturbation. Then, the robustness of the system are improved.

仿真实验结果表明，采用本文方法设计的鲁棒二自由度控制器性能很好，不但保证了伺服系统的动静态性能，而且降低了系统对控制器参数摄动的灵敏度，提高了系统的整体鲁棒性能。

This paper shall attempt to look at some aspects of controller synthesis for the multivariable servomechanism problem when the plant to be controlled is subject to uncertainty-in this case,a controller is to be found so that satisfactory regulation/tracking occurs in spite of the fact that the parameters of the plant may be allowed to vary,subject only to the condition that the resultant perturbed system remains stable.

例7 本篇将致力于探讨在待检对象受到不确定性的影响，而仅仅服从受扰动的系统最终保持稳定，这一条件之情况下的多变量随动系统中控制器综合的某些方面的问题。在这种场合，尽管受控对象的参数允许发生变化，而控制器必须具有令人满意的调节和跟随性能。

The user insets the money into the slit, and then the coin recognizer identify the inserted money and add it up; then the MCU sends out the signals about sellable goods by lighting the pilot lamp, so that the user can choose what he or she wants to buy; following the user presses the key related the goods which he or she wants to buy, and then the key makes single chip to start relevant parts to push out the goods, and now the buyer can get the goods. If there still left enough money, the user can buy another goods.

用户将货币投入投币口，货币识别器对所投货币进行识别；控制器根据金额将商品可售卖信息通过选货按键指示灯提供给用户，由用户自主选择欲购买的商品；按下用户选择商品所对应的按键，控制器接收到按键所传递过来的信息，驱动相应部件，售出用户选择的商品到达取物口；如果还有足够的余额，则可继续购买。

The second strategy is a two-stage iteration policy for the design of a liveness-enforcing controller, which includes a siphon control stage and an augmented siphon control stage. After that, there is no maximal deadly siphon in controlled system such that the liveness can be preserved.

第二种策略是两阶段的活性控制器设计迭代算法，通过信标控制和导出信标控制两个阶段使系统不会产生新的死信标从而保证了控制器的活性。

By the proposed fuzzy adaptive robust: controller there is no need to find a comrnon positive definite matrix satisfying matrix Lyapunov equation.

整个控制方案在结合所有的局部线性状态反馈控制器的基础上，引入了基于自适应神经网络的鲁棒控制器。

Under the fixed power, the different controller parameter at the different rod positions can satisfied for the preconcerted control index and control performance.

充分发挥数字化控制器的优点，在同一功率定值、不同棒位下，采用不同的控制器参数能较好地满足预定的控制指标和性能要求。

The experiment analized the effection produced by changing the a predial single-neuron PID controller's parameter.

实验分析了单神经元PID预测控制器参数对性能的影响，并与普通PID控制器作比较。

Especially, the controller preserves the equilibrium of the nonlinear system.

特别地，所设计的控制器还能保证控制器的平衡条件。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
